I've tried everything that I could think of and everything that came up
by googling the problem. After a few minutes, whether the screensaver is
on or not, whether the power management is enabled or not, whether the
require password button is checked or not, the screensaver will start and
require a password to log back in. Surprisingly, it does select the
screensaver that was last checked, even when it's not set to come on.
It's getting a little bit annoying. Are there any suggestions?
